AS-Interface Slaves

•Well-proven terminal system

•Secured against detachment and vibration

•Safety against finger touch

•Labeling

The AS-Interface module series for the "SlimLine“ control cabinet to the degree of protection IP20 creates space in the control cabinet or in the distributed on-site control box.

The emphasis of this module series is on its slim design. The modules are 22.5 mm or 45 mm in width.

Via screw-type or Cage Clamp terminals, standard sensors/ actuators and the AS-Interface cable can be connected.

Integrated adapters allow the modules to be mounted on stan- dard rails. Deinstallation from the standard rail is quick and easy without the need for tools.

The modules can also be screwed in place by an additional accessory.

All modules have LEDs on the front which indicate the status of the module.

An addressing socket built into the front allows addresses to be assigned in the installed state.

Apart from the digital input and output modules, modules with special functions are also available in S22.5 format. These in- clude:

•Counter module

•Earth fault detection module

For further information on these modules, see the Section AS-Interface / Modules with Special Functions.

The removable terminal is the innovative connection technique from Siemens for AS-Interface SlimLine modules of the S22.5 and S45 Series. The complete terminal block can be quickly and easily dismantled and reassembled. It is not necessary to dis- connect the terminals during this process.

Note

•The devices will be converted from 2004 and will be available under the same order number.

•Before the terminal block is removed, the device must be dis- connected from the supply.

The complete ease of handling for connecting wires is retained in the design of the new removable terminals. The familiar con- ductor cross sections can continue to be used.

•Variable connection techniques

All modules are available with screw-type or Cage Clamp ter- minals.

•Coding

The terminal blocks cannot be mistakenly interchanged thanks to coding (EN50178).

The terminal blocks are latched into the housing. The terminal blocks can be removed using a screwdriver VDE0100T410 (IEC-4-41). Inadvertent removal is therefore not possible.

Even in the removed state, the contacts of the modules are safe against finger touch according to DIN 61140(IEC 60529).

All terminal connections are labelled on the terminal block

which makes preassembly possible.
